I truly prefer to sight my big game hunting rifles dead on at 200 yrds. For most of them it ranges from 1.1 to 1.5" high at 100 yards. But you won't know for sure if it is dead on at 200 yards unless you shoot your rifle at that distance. My elevation is between 7,800-12,500 feet the trajectory is a tad different than sea level so I don't go buy what the manuals say I find the drops on paper at the range. But some of the new ballistic calculators online are pretty close if your dealing with elevation changes. A lot of guys are going to the idea of using a maxium point blank range zero for practical hunting applications. Which if I hadn't had my drops programmed in my head for decades it would seem like the logical thing to do. You'd be dealing with just a few inches of rise and drop in elevation from 0 to 300 yards in most rifles in that 3000 fps mark.
